Hi Bob - HD files arrived today. Many thanks.
Wouldnt play on PC either. Blind leading the blind but I downloaded
Haali Media Splitter. I understand that this splits the file up and sends the relevant bits to the right decoders. It played fine but with a MainConcept logo (I had downloaded their trial encoder last week). I downloaded ffdshow to get the necessary codec (I think) without a logo and all works well. That said I have a P4 3Ghz and its choppy. Not sure if I had downloaded ffdshow and not the HMSplitter if it would have worked.
Have put them on my USB drive and will watch tonight on the big screen. Those lucky BBCHD trialists - the quality looks fabulous. I really hope this is going to be the norm very soon.
Cheers Bob.
